PHP MySQL PDO lastInsertID causes fatal error

Question

I tried looking through some other posts, but didn't see anything exactly what I'm looking for.

I have a DB query

$sql = "INSERT INTO groups(Name) VALUES (:name)";
$dbs = $dbo->prepare($sql);

$dbs->bindParam(":name", $_POST['name'], PDO::PARAM_STR);

$dbs->execute();

$groupID = $dbs->lastInsertId();

That returns this fatal error:

[Tue Dec 20 13:59:23 2011] [error] [client 127.0.0.1] PHP Fatal error:  Call to undefined method PDOStatement::lastInsertId() in /media/Storage/www/2011/admin/public/ajax.users.php on line 87, referer: http://localhost/2011/admin/public/menu.php?page=users

According to the php manual for PDO::lastInsertId():

If the PDO driver does not support this capability, PDO::lastInsertId() triggers an IM001 SQLSTATE.

How would I determine if my server supports lastInsertId()? I do not see IM001 in my error log anywhere.

When I run this, the data is inserted fine, but I cannot get its ID to use in the next set of INSERT's that set the group permissions.

Answer 1

lastInsertId() is a method of the PDO class, not the PDOStatement class.

This should work:

$groupID = $dbo->lastInsertId();
